How MT cells analyze the motion of visual patterns

Rust, Nicole C, Mante, Valerio, Simoncelli, Eero P, Movshon, J Anthony·2006·Nature Neuroscience

Abstract

Neurons in area MT (V5) are selective for the direction of visual motion. In addition, many are selective for the motion of complex patterns independent of the orientation of their components, a behavior not seen in earlier visual areas. We show that the responses of MT cells can be captured by a linear-nonlinear model that operates not on the visual stimulus, but on the afferent responses of a population of nonlinear V1 cells. We fit this cascade model to responses of individual MT neurons and show that it robustly predicts the separately measured responses to gratings and plaids. The model captures the full range of pattern motion selectivity found in MT. Cells that signal pattern motion are distinguished by having convergent excitatory input from V1 cells with a wide range of preferred directions, strong motion opponent suppression and a tuned normalization that may reflect suppressive input from the surround of V1 cells.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Subjective VQA is impractical for nearly every application other than benchmarking automatic or objective VQA algorithms.

    “Subjective VQA is impractical for nearly every application other than benchmarking automatic or objective VQA algorithms.”
  • The models in [58], [72] are rather elaborate, physiologically plausible mechanisms designed to match the properties of visual neurons, while our model is designed from an engineering standpoint of capturing distortions in videos.

  • The temporal quality computation bears several similarities with the neuronal model of MT, including the weighting procedure based on distance between linear filters and the motion plane and the normalization of weighted responses.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
